(3) Errors when calling data from API using Contentful & SwiftUI

Forgive me as I am extremely novice with SwiftUI... I am attempting to pull data from the CMS and put it in my app however it is throwing three errors on each attempt for the data to be retrieved and placed...

The errors are highlighting in the sections that read "api.beers.title", "api.beers.type" and "api.beers.description".

Errors

API Call Code

func getArray(id: String, completion: @escaping([Entry]) -> ()) {
    let query = Query.where(contentTypeId: id)

    client.fetchArray(of: Entry.self, matching: query) { result in
        switch result {
        case .success(let array):
            DispatchQueue.main.async {
               completion(array.items)
            }
        case .failure(let error):
            print(error)
        }
    }
}

class API: ObservableObject {
    @Published var draft: [Draft] = draftData

    init() {
        getArray(id: "beers") { (items) in
            items.forEach { (item) in
                self.draft.append(Draft(
                    title: item.fields["title"] as! String,

  1. Your draft is array, you can access by index like Text(api.draft[0].title)
  2. @Published var draft: [Draft] = draftData instead @Published var draft: [Draft] = []

Updated:

class API: ObservableObject {
    @Published var draft: [Draft] = [] 

    init() {
        getArray(id: "beers") { (items) in
            items.forEach { (item) in
                self.draft.append(Draft(
                    title: item.fields["title"] as! String,
                    type: item.fields["type"] as! String,
                    description: item.fields["type"] as! String
                ))
            }
        }
    }
}

struct DraftList: View {
    var width: CGFloat = 275
    var height: CGFloat = 200
    @ObservedObject var api = API()
    var body: some View {
            VStack {
             ForEach(api.draft) {item in 
                Spacer()
                Text(item.title)
                    .font(.system(size: 24, weight: .bold))
                    .padding(.horizontal, 20)
                    .frame(width: 275, alignment: .leading)
                    .foregroundColor(Color("TextColor"))
    
                ...
             }
            }
            .padding(.horizontal, 20)
            .frame(width: width, height: height)
            .background(Color("TileOrangeColor"))
            .cornerRadius(15)
            .shadow(color: Color.black.opacity(0.2), radius: 5, x: 0, y: 5)
        }
    }
